I bought a contour design shuttle pro v2, but I don't know how to make it work.

I installed the device driver, and mach3 plugins (mach version 2.0 g), switches are working, but the wheel doesn't work why?
What I have to do?

Thanks a lot

I installed the latest version of mach3 and now it works, but i don't think it work ok

Look at the video here www.fxmodel.it/shuttle.wmv  is how it does.

Thanks Fab

Do NOT install the shuttle software. If you did, uninstall it. All you need is the plugin.

I did it... 
I uninstalled it, now it's ok.

Thanks
